In the post-pandemic era, the beverage and pharmaceutical industries have witnessed a 40% surge in demand for hermetic sealing solutions. Mesin can sealer technology is at the heart of this revolution, ensuring product longevity and tamper-evident security. Global enterprises are now shifting toward PET and metal hybrid solutions to balance sustainability and shelf-life.
Demand in Southeast Asia is driven by the booming "Grab-and-Go" beverage culture, while the North American and European markets prioritize CE-compliant and BPA-free material handling. Our factory provides specialized voltage and safety adaptations for 50+ countries, meeting rigorous local compliance standards.
Standard machines offer 95% efficiency, but Copak's proprietary Smart-Seal AI sensors achieve 99.9% seal integrity. This "0.1% defect" engineering prevents micro-leakage, which is critical for carbonated beverages and nitrogen-flushed snacks.
Established in 2021, Shanghai COPAK Industry Co., Ltd. maintains a strategic sales office in Shanghai and an advanced associated factory in Guangdong Province. As a professional supplier of eco-friendly food and beverage packaging solutions, our portfolio includes PET cups, PET cans, and high-performance sealing machines.
Committed to staying ahead of market trends through continuous innovation, COPAK delivers cost-effective yet premium-quality packaging solutions. Our range covers capacities from 1oz to 32oz, supporting both plain and High-Definition Custom Printing.

We aren't just building machines; we are architecting the next generation of food safety and automation.
Transitioning from cam-driven to full servo-motor control systems. This allows for millisecond adjustments to sealing pressure, compatible with even the thinnest rPET materials.
Integration of real-time vibration and thermal analysis. Our Mesin can sealers will predict mechanical wear before it causes downtime, integrated via cloud-based monitoring.
A "One-Machine-All-Sizes" approach. Automated tooling changes that allow a factory to switch from 202# to 307# lid diameters in under 3 minutes.
High-carbonation retention seals for sparkling juices and nitrogen-infused coffee (Nitro-Brew).
Vacuum-sealed PET cans for snacks, nuts, and dried fruits, extending shelf life by up to 300%.
Corrosion-resistant sealing components for specialized industrial liquids and beauty products.
Fully compliant with ISO 9001:2015, FDA food-grade standards, and SGS certification for export.
Q: What is the main cause of leakage in PET can sealing?
A: Leakage is typically caused by inconsistent sealing pressure or a mismatch between the lid curl and the flange of the PET can. Our high-quality Mesin can sealers utilize precision rollers that apply uniform 360-degree pressure, compensating for material variations.
Q: Can one sealing machine handle different can diameters?
A: Yes, Copak machines are designed with modularity. By changing the base mold and the sealing chuck, a single machine can handle various diameters, though height adjustments are usually much faster than diameter changes.
Q: How does nitrogen flushing benefit the sealing process?
A: Nitrogen flushing (optional in our automatic models) removes oxygen, preventing oxidation. This is essential for maintaining the flavor profile of cold-brew coffee and the crispness of nuts.
Q: What is the maintenance cycle for a factory-grade sealer?
A: We recommend a minor inspection every 500,000 cans and a major overhaul of the rollers every 2 million cycles. Our machines feature Self-Lubricating Bearings to extend these intervals.
